STYLE: Remove trailing whitespace in Fortran files

This is mostly a long term maintenance improvement.

Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.

By removing whitespace on one patch, it makes future
code reviews much easier.

if which tempfile &>/dev/null; then
  TEMPMAKER=tempfile
elif which mktemp &>/dev/null; then
  TEMPMAKER=mktemp
else
  echo "Cannot find tempfile program." 2>&1
  exit 1
fi

MYTEMP=$($TEMPMAKER)
trap 'rm -f $MYTEMP' SIGINT SIGTERM

stripit() {
  echo "stripping $1"
  sed 's/[ \t]*$//' "$1" > $MYTEMP
  cp $MYTEMP "$1"
}

if [ $# -gt 0 ]; then
  while [ "$1" != "" ]; do
    stripit $1
    shift
  done
else
  while read -t 2; do
    stripit $REPLY
  done
fi

rm $MYTEMP
